Each diet was fed to catfish in triplicate tanks for 8weeks. Results show that a 1% Dragon Well tea (DWT) and Maofeng tea were significantly better than other diets (including the control) in improving weight gain (WG) and feed conversion rate (FCR) of fish; while the 4% DWT increased FCR (P<0.01) but decreased WG (P<0.05). In addition, 4% DWT resulted in a significant decrease in muscle lipid content. Pu-erh tea in 2 and 4% dietary addition decreased saturated fatty acid and increased monounsaturated fatty acid content in muscle. The hepatosomatic index decreased significantly in fish fed the 4% DWT diet. The mortality (%) of catfish challenged with A. hydrophila decreased with increasing addition of tea to the diet, and the mortality in DWT and Huangya tea (HYT) was lower than control groups (P<0.05). In conclusion, diets supplemented with a low dose (1%) of Chinese tea increased growth performance and enhanced the fish fillet quality. Addition of DWT or HYT tea at 4% in channel catfish diets can improve resistance against A. hydrophila, but growth performance is reduced.
